有钱能使鬼推磨?研究称:锻炼靠自觉 给钱没用

2017-08-18 06:57:16   新华网

中国有句老话叫“有钱能使鬼推磨”。不过美国凯斯—西部保留地大学(又称凯斯西储大学)的一项最新研究则显示,在锻炼身体这件事上,就得靠自觉,金钱奖励起不到什么作用。

研究人员招募836名志愿者,承诺他们如果在6周里坚持去9次健身房,就可以得到奖励,奖品包括价值30美元(约合200.6元人民币)的亚马逊礼品卡、一台食物搅拌器或同等价值的实物礼品、价值60美元(401.2元人民币)的亚马逊礼品卡。另有一组对照组也被许诺事后可以得到亚马逊礼品卡,但金额需视他们去健身房的次数而定,且奖励金额低于前者。研究人员在递交美国全国经济研究所的报告中写道,第一周结束后,14%的研究对象不再去健身房。他们还发现,到最后一周时,金钱奖励也没能激励研究对象更多前往健身房;奖励多的一组并没有比对照组多去健身房。总体来看,就激励人多去健身房锻炼而言,金钱奖励的促动作用体现为平均每周多出0.14次。

英国《每日邮报》援引研究带头人玛丽安娜·卡雷拉的话报道,“看来,促使一个人开始锻炼的内在动机与金钱无关”,锻炼就是靠自觉。(乔颖)【新华社微特稿】
